The buoyant force must be equal to the force of gravity on the boat or the boat would accelerate upwards or downwards. ~1.545*9.8 * 10 ^ 3 N

2. The weight of water displaced must be equal to weight of the boat. If the water has a density of 1000kg / m^3 then the 15450 kg of water has a volume of 15.45 m^3
